“I said, ‘Don’t shoot him. Don’t shoot my dog. He won’t bite you.’ But he shot him, just like that. It all happened in under 30 seconds,” Paxton said. “There was no attack on the officer other than barking and challenging him.”

Austin Police Cpl. Anthony Hipolito told ABCNews. com that the officer did respond to the wrong address, but it was the address provided by the 911 call. The call came from the house next to Paxton’s.

Hipolito said that dashcam footage shows the dog barking and attacking the officer.

“The officer was basically in retreat and asked the owner to grab the dog,” Hipolito said. “He was unable to and the dog continued to attack and that’s when the officer discharged his firearm.”

An apology was issued at the scene, according to Hipolito, but Paxton said no one apologized to him.

Paxton is heartbroken over his dog’s death and calls the incident a “senseless tragedy.” A Facebook page demanding “Justice for Cisco” has garnered 42,000 likes in three days.
